Tae collection of Astzrorpea is one of the most important made during the voyage of the Challenger. The late Sir C. Wyville Thomson paid con- siderable attention to these organisms, and at one time had the intention of describing the new species discovered during the Expedition; with this end in view, indeed, he had a few of the specimens figured and_litho- graphed. Eventually, however, the whole collections were handed over to Mr. W. Percy Sladen for examination and description. The result of Mr. Sladen’s work, extending over many years, is now presented in this magnificent Report, which forms Part LI. and Volume XXX. of the Zoological series of Reports, the text and plates being bound up in separate parts. Not only on account of the large number of forms, but also on account of their representative character, the Challenger collection is unquestion- ably the most important contribution to this group of animals that has ever been made. In the Report, supplementary to the treatment of the Challenger material, a compact account of the whole group has been aimed at. Thus (1) under each family an account of all the genera included therein, whether Challenger or not, has been given, and where necessary the grounds on which the classification has been adopted are discussed; (2) under each genus there is a statement of all the known species which are recognised as belonging to that genus, with an account of their geo- graphical distribution: this presents a compact idea of the composition and distribution of each genus ; (3) a complete list of all the known species of THE VOYAGE OF H.M.S. CHALLENGER. recent Asteroidea, with their geographical and bathymetrical distribution, and a full account of all synonyms and changes of name are given; every known starfish is believed to be included, and the recognition of “ good species ” and “synonyms” is based on personal observation (except in the case of some American types and a few recently described from the French dredgings). The Report may be considered a monograph on the group, though of course it need hardly be said that previously described and recognised species are not re-described. An entirely new classification of the Aster- oidea has been given—it was very unsatisfactory and quite unworkable previously. All naturalists who appreciate careful and accurate work will join with me in congratulating Mr. Sladen on the completion of his valuable memoir, which extends to 935 pages, and is illustrated by 118 lithographic plates and a map.
